Gyrokinetics

Gyrokinetics is a specialized approach used in plasma physics to study the behavior of charged particles, like ions and electrons, in magnetic fields—especially in fusion reactors. It simplifies complex motion by focusing on the particle’s rapid circular (gyro) movement around magnetic field lines, allowing scientists to analyze slower, more relevant changes without tracking every tiny detail. This approach helps understand how plasmas behave under magnetic confinement, aiding in the development of controlled nuclear fusion as a potential energy source.
